Hi friends.
I have recently did it and move to MIUI rom.
This rom is perfect! The music player, the speed, the non-crashing thing..
But one thing doesen't works.
In can't apply any themes, lockscreen, background..
all time when i trying to download/apply, it crashing..
In have MIUI mcgv 7.6 and samsung galaxy s 1.
Thank you!!
